You can use ITEQ no flow prepreg for Rigid-Flex Boards and any other application that requires uniform and low resin flow characteristics.
What Is The Difference Between ITEQ Core and ITEQ Prepreg?
These two materials are both used in the fabrication of multi-layer PCBs.
An ITEQ core is the primary material you need to manufacture your ITEQ PCB.
In some cases, the core and laminate may be used to refer to similar materials.
A PCB core is, therefore, a material layer that has copper foils attached to both sides.
The core can either comprise single or multiple prepreg laminates that have undergone pressing, hardening, and heat curing with both of its sides plated with copper.
On the other hand, a prepreg is a PCB base material such as glass fibres that have been reinforced with a resin system and hardened but not yet cured.
Prepreg is a bonding material that acts as a glue that bonds several core materials together.
When you place a prepreg between two adjacent core and expose it to heat, the resin will melt and start bonding the adjacent layers.
Finally, the resins harden and cure through crosslinking.
You can also use ITEQ prepreg to insulate the inner conductive pattern of multiple layer boards.
What is an ITEQ Copper Clad Laminate (CCL)?
An ITEQ CCL is a base material for constructing PCBs.
It comprises an organic reinforcing material such as fibreglass or pulp fibres that have been impregnated with adhesive resin and laminated on both sides with copper foil at high temperature and pressure.

How Can You Test the Efficiency of ITEQ Laminate?
You can use different methods to test ITEQ laminates’ qualities as specified by IPC and ASMT standards.
Some of the test methods you can use include:
· Stripline Resonators
This test helps you determine the laminates Dk and Df values at up to 10GHz.
You can also use other methods to determine these properties though they will give different results.
For this reason, you always have to specify the test you used.
· Thermochemical Analysis
Test for laminate’s volumetric change when subjected to heat.
It gives the laminates CTE and also its transitional temperature, though indirectly.
· Infrared Spectrophotometry (IR)
It shows changes in laminate’s chemical properties through absorption and transmission of infrared frequencies.
· Laser Flash Thermography
This test gives the laminate’s bulk density, specific heat, and thermal diffusivity that you will use to work out the material’s thermal conductivity.
· Thermogravimetric Analysis (TGA)
TGA mainly test for the decomposition temperature and its rate of progression.
However, the test will also give the content volatiles, moisture, and ash residue.
· Differential Scanning Calorimetry (DSC)
This test method gives you the melting point of your ITEQ laminate.
It also provides the temperature and level of laminate’s curing.
Is Halogen-Free and Lead-Free ITEQ Laminates Refer to The Same Technology?
Halogen-free and lead-free standards are fabrication measures that protect people’s health and the environment from hazardous chemicals used in fabricating PCBs.
Lead-Free ITEQ Laminates
Lead-free laminates refer to PCB laminates that are RoHS compliant.
These laminates have been produced following RoHS requirements or Directive 2202/95/EC.
RoHS compliance directives were first implemented in European Union in 2006.
It focuses on restricting the use of hazardous compounds in the manufacture of PCB and other electronic products.
Presently, your products must adhere to these standards if they are to be accepted in European Union.
The standards have also been adopted by other major government agencies worldwide.
RoHS standards specify the maximum allowable quantities on the following restricted products on PCBs and other electronics as listed below.
|Mercury||< 100 ppm|
|Lead||< 1000 ppm|
|Cadmium||< 100 ppm|
|Hexavalent Chromium:||< 1000 ppm|
|Polybrominated Biphenyls||< 1000 ppm|
|Bis(2-Ethylhexyl) phthalate||< 1000 ppm|
|Polybrominated Diphenyl Ethers||< 1000 ppm|
|Dibutyl phthalate||< 1000 ppm|
|Benzyl butyl phthalate||< 1000 ppm|
|Diisobutyl phthalate||< 1000 ppm|
Using lead-free ITEQ PCB laminates will help you improve your products’ safety, improve their thermal properties and reduce metal poisoning.
Halogen-Free ITEQ laminates
A halogen-free ITEQ laminate has been constructed according to the halogens’ set limits, chlorine, bromine, and fluorine).
Brominated flame retardants have been previously used to manufacture laminates to reduce damages and injuries associated with fire.
However, modern constructions of laminates avoid using such halogen-based techniques due to health and environmental concerns.
The problems associated with halogen used in laminates and other electronics come at the end of the product life cycle.
Disposing halogen-based laminates and electronic materials through incineration releases toxic halogen gases that can cause serious health problems when inhaled.
Many standards allow different maximum levels of halogen in an electronic product.
IEC standards identify halogen-free products to contain less than 900 ppm of chlorine and bromine and less than 1500 ppm of total halogen content.
Other benefits of halogen-free laminates are:
- Lower Coefficient of Thermal Expansion
- Higher transitional and decomposition temperatures
- Can tolerate higher reflow temperatures and cycles.
What Is the Shelf Life of ITEQ Laminates?
The shelf life of ITEQ laminate significantly varies depending on the handling, shipment, and storage conditions.
Usually, the handling and shipment conditions are overlooked, but they are just as important as storage conditions.
You should carefully handle ITEQ laminates to avoid contaminating or damaging them through scratches, dents, etc.
Similarly, transport your laminates in temperature-controlled chambers to prevent moisture attacks that would otherwise damage the laminates.
Storage of your ITEQ laminates is the most sensitive aspect with a direct influence on their shelf life.
The ultimate secret is to store your laminates at a standard room temperature range of between 13C to 28C and low humidity.
Since laminates are fully cured products and cannot advance further, you can store them for almost eternity in cool, clean, and dry conditions.
Avoid exposing the laminates to direct radiation, UV light, and other degrading agents while in storage.
Should you realize some oxidation on the copper foil, you can still recover the laminate’s original specs either through baking or using standard pre-cleaning techniques.
What Factors Affect the Cost of ITEQ Laminates?
The price of ITEQ laminate depends on the following:
- The laminate’s thickness and panel size
- Type of copper cladding used
- The dielectric constant and dissipation factor of the laminate
- The thickness of copper cladding
- The laminate’s mechanical properties
- Laminate’s thermal properties
- Cost of shipment
- Quantity purchased
- Taxes and tariffs, etc.
